maximum heap size limitations on Windows 32-bit

807607Oct 13 2006 — edited Oct 16 2006
Developing a memory - intensive application, I'm currently limited by the heap size of my jvm. Using -Xmx or -XX:AggressiveHeap options did not help : I'm still unable to allocate more than 1GB (50% of my RAM) to my jvm. When setting -Xmx to more than 1GB, the java command fails with "Could not create the Java virtual machine" error

I'm using JSE5.0 on a 2 CPU - 2GB -32 bit Windows XP 2002 professional.

Is that a limitation of Windows 32-bit ? I've read that Windows kidnaps 50% of RAM for kernel/system purpose...

I'm also using the "-server" option for performance reason : may that be influent on available heap size ?

Can any one help me ?

Thanks
